Another moisture loving perennial at Glin is Darmera Peltata, commonly known as the umbrella plant.

It is known as the umbrella plant but I find it more reminiscent of a fireworks explosion.

Add a small water plant (such as a dwarf umbrella plant) in a bonsai dish, rocks, a submersible pump, and a bamboo spout that's a variation of the traditional Japanese deer scarer, or shishi odoshi (often sold at nurseries).
